Prevalence of Chronic Middle Ear Effusion in Cases of Cleft Palate

Chronic middle ear effusion is generally present in children with cleft palate (CP) associated with or without cleft lips. The aim of our study was to assessment of how common middle ear effusion is in patients with cleft palates and to evaluate the presence of these symptoms by performing a Basic Audiological Evaluation (BAE). A retrospective randomized study was conducted on 50 children (29 male and 21 female) aged 2 to 16 years who had CPs (associated with or without cleft lips) with symptoms of middle ear effusion. The study was conducted from March 2021 to February 2022. Data review included the results of otoscopic findings and BAE. The Fundamentals of BAE comprise the testing of middle ear function with tympanometry and a pure tone audiometry to determine the kind and degree of hearing impairment. Regarding the BAE, we found that 70% of the children with normal hearing, 24% with conductive type of hearing loss, and 6% with mixed type of hearing loss. The tympanometric results revealed that 66% of the children with type A tympanogram, 24% with type C tympanogram, and 10% with type B tympanogram. The contralateral stapedial reflex was present in 60% of the patients while in 40% of cases not present. The results confirmed the great prevalence of chronic middle ear effusion in children with CPs. Furthermore, the hearing impairment associated with middle ear effusion was visible, demonstrating that middle ear effusion was linked with the prevalence of moderate conductive type of hearing loss. The OME in cases of CP necessitates early prediction and in turn early treatment.
